Application filed October 5, 1911. l Serial No. 652,913.

To all whom it may concern:

Be it known that I, WILLIAM J. STEELE, a citizen of the United States,residing at Sterling, in the county of Rice, State of Kansas, haveinvented certain new and use'- ful Improvements in Plow Attachments; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to plow attachments and particularly toattachments for lister plows.

The object of the invention resides in the provision of an attachment ofthe character named which includes a pair of disks and means wherebysaid disks may be adjusted bodily toward and away from each other andalso adjusted so as to be disposed at different angles to thelongitudinal axis of the plow, said adjust-ments of the disk beingresorted to in order to eect the return of the proper quantity of soilto .the furrow formed by the plow share.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

yIn describing the invention in detail, reference will be had to theaccompanying drawings, wherein like characters of reference denotecorresponding parts in the several views, and in which- Figure 1 is aside elevation showing the attachment applied to a lister plow, Fig. 2,a plan view of what is shown in Fig. 1 with the attachment in full linesin one posit-ion and in dotted lines in an adjusted position, Fig. 3, aview similar to Fig. 1 showing the disks of the attachment in full linesdisposed at a given angle to the longitudinal axis of the plow and indotted lines adjusted to another angle to said axis, Fig. 4, a sectionon the line 4-4 of Fig. 1, and Fig. 5, a section on the line 5-5 of Fig.2.

In the drawings there is shown an ordinary lister plow comprising a beam10 the rear end of which is curved rearwardly and downwardly to form astandard 11 which latter has secured to its lower end a mold board 12.Mounted upon the standard 11 at the upper edge of the mold board 12 bymeans of bolts 13 are blocks 14 having rearward enlargements orextensions 1,5. These extensions 15 are provided with vertical openings16 and 17 in which are mounted respectively corresponding arms ofU-shaped brackets 18 and 19. These arms of said brackets are 0f a sizeto be rotatable for adjustment in the openings 16 and 17 whereby thefree ends of the brackets may be swung toward and away from each otheras desired. The arms of the brackets 18 and 19 which` are disposed inthe openings 16 and 17 are held against rotation when desired 4by setscrews 2O mounted in the extension 15 and adapted to impinge, whenmanipulated, against the arms of the brackets.

The attachment further includes disks 21 and 22 carried respectively atthe free ends of the brackets 18 and 19 respectively.

Each of the disks 21 and 22 have secured thereto a laterally extendinghub 23 having a longitudinal opening 24 therethrough. This hub 23 isprovided with a lateral flange 25 which is directly secured torespective disks by means of bolts 26. Surrounding the hub 23 of eachdisk is a boxing 27 in which said hub rotates. This boxing 27 isprovided with an extension or enlargement 28 provided with an opening 29in which the outer arm of respective brackets 18 and 19 is disposed soas to permit adjustment of the boxing 27 upon said arm. In order to holdthe boxing 27 against rotation on respective arms of the brackets 18 and19 there are mounted in the extensions 28 set screws 30 which may beoperated to impinge upon the arms of the brackets disposed in theopenings 29. Mounted upon the boxing 27 so as to feed upon the hub 23within said boxing is an oil cup 31. The boxing 27 is secured againstlateral displacement of the hub 23 by means of a cap 32 secured againstthc outer end of said hub by a bolt 33 passing through the opening 24,said cap overlapping the adjacent end of the boxing 27.

By this construction it will be apparent that the brackets 18 and 19 canbe adjusted toward and away from each other by swinging same on theirinner ends which will result in the disks 21 and 22 being disposednearer together or farther apart as the case may be. Again by rotatingthe boxings 27 on the outer arms of respective U-shaped brackets 18 and19 the disks 21 and 22 may be adjusted to different angles with respectto the longitudinal axis of the plow and this last named adjustment ofsaid disks together with their bodily adjustment previously mentionedwill enable the plow to be regulated so that the proper quantity of soilwill be returned to the furrowlformed 5 by the plow share.

What is claimed is:

locking said brackets i n adjusted position, a

boxing adj ustably mounted on the other arm of each bracket, means forlocking said boxing in adJustment, and disks each provided 15 with a'hub journaled in said boxings re spectively.

In testimony whereof, I aIiX my signature, in presence of two wltnesses.

VILLIAM J. STEELE.
